How I can get the attachment from a mail in WSO2 ? I able to get the subject and body of the mail. I need to fetch an attachment file in the mail. How it could be done ? I'm using Gmail POP3 server.
There is nothing specific whether the mail is from some WSO2 server or not. If you have attachments, that implies the mail uses multipart/form. Therefore you can process it as a multipart/form message. There are a lot of libraries that you can use to do the parsing. e.g. Apache Commons, Javamail or you can use normal java URL connection and carefully work with the mime boundaries.
We used to parse the whole message body looking for boundries of attachments, then apply Base64Decode to substracted pieces, then operate with them like binaries.
Sorry, I do not have that synapse-config right now, can not tell you exactly what to do.

I want to forward all mail for root (so basically the output of all cron jobs but other mails for root as well) to an external email address (hotmail).
Easiest method would be to use the aliases file. I updated the root alias:
root: mymail#hotmail.com
And ran newaliases.
When an email is sent I see that the hotmail MX server "accepts" my mail. Standard MS Security through obscurity makes me think it's silently discarding my email ( not in junk mail, ... ).
This server is used to send/receive mail for a domain (and more domains in the future).
I've checked the logs and it seems the mail is sent with from field of : root#mail.domain.com
I'm pretty sure this is at the root of my mail never received in my hotmail.
The existing email addresses are using user#domain.com as from.
Now I would like to rewrite this (mail) from address/ctladdr.
I thought this would be an easy fix with genericstable.
Genericstable (had multiple tries):
root info#domain.com
root#localhost info#domain.com
root#mail.domain.com info#domain.com
Regenerated the db with makemap.
I tried with different settings.
I also removed the EXPOSED_USER root (from the generic m4 file). I can see it's not in the generated cf file.
I also added root to the trusted users.
In my m4 file:
FEATURE(genericstable)dnl
GENERICS_DOMAIN(domain.com)dnl
dnl GENERICS_DOMAIN(mail.domain.com)dnl
dnl GENERICS_DOMAIN_FILE(`/etc/mail/generics-domains')dnl
FEATURE(masquerade_envelope)dnl
dnl define(`LOCAL_RELAY', `localhost')dnl
I have a submit mc file as well. Not sure if this matters but I don't think so.
(I don't have sendmail in MSP mode running as far as I know).
I've tried with GENERICS_DOMAIN as the domain that I want it to be or the domain that I want to be rewritten.
make all install
and restarted sendmail.
Still it just seems to go out as root#mail.domain.com
I tried with sendmail in address test mode (bt; tryflags hs and try esmtp root). This correctly modifies to the wanted source address: info#domain.com.
Anyone has some other ideas why this is not working? Or more debugging ways?
Do I need local_relay to make this work? What's expected to be in the hosts file? Fqdn(mail.domain.com) and hostname(so mail) for 127.0.0.1 ?
EDIT: I probably should mention that I have an incoming queue for MailScanner.
Thanks a lot in advance!
I believe the source of my issue is that I was expecting all mailserver mentioned in the headers to have the mail.example.com removed.
However the first header is to submit it to the local queue.
And only when Sendmail is sending the mail out (connecting to the outside MX of example.com) the translation gets done.
So the servers mentioned in the headers stay with mail.example.com.
I thought the mail.example.com was the culprit in hotmail not delivering my email. Which seemed to be wrong.
After investigating for a long time I noticed that if I sent an email from info#example.com to hotmail it was nowhere shown(no, not even in spam, ...) while it was accepted.
If I sent an email first to info#example.com and then sent one back from info#example.com the mail gets successfully delivered in the hotmail mailbox.
This also seems to be the case with other users of the same example.com domain (so not solely with info#).
After some more investigating I noticed: html email seems to be more easily delivered(sent through squirrelmail). Plain text only mails seem to be ignored.
NOTE: in all cases my mail was accepted by the hotmail mailserver. So no error code 550 or something. I was always sending mail from the mail.example.com server (either command line or through Squirrelmail).
EDIT: I had yet another annoying encounter with Hotmail. Again my message is accepted and just disappears. I've been sending to this destination address before without any issues. But for some reason all of a sudden Hotmail mailservers get "improved".
I'd like to throw in this reference of a topic that got opened years ago which is still ongoing with no feedback from MS: https://answers.microsoft.com/en-us/outlook_com/forum/oemail-osend/messages-reported-as-250-queued-for-delivery-but/f451cda5-ba7d-45ff-b643-501efe2413dc?page=2 . So you're definitely not alone. But also understand that there can be multiple issues leading to the same symptoms.
So I'd like to add some steps which might help preventing a massive headache for others:
Use a footer that clearly states your company and domain.
Use HTML mail
For some reasons sometimes I see mails getting delivered directly in the Deleted folder. Not in Spam
For some reason sending more mails from your domain is better as you gain more "reputation"
You can open a case with Microsoft here:
https://support.microsoft.com/en-us/getsupport?oaspworkflow=start_1.0.0.0&wfname=capsub&productkey=edfsmsbl3&locale=en-us&ccsid=635754176123391261
Don't set your expectations high. They'll mainly send you an email back that you're not eligible for remediation and later on answer on your case with a standard answer. HOWEVER what creating this case does do is probably getting confirmation that your email got indeed "filtered" by the mighty SmartScreen (they will not tell you why). But this way at least you know it's the spam filter and the below points might help you out.
Make sure to pass the message ID, timestamp, ... (log entry from maillog is what I did)
The answer on your case will certainly mention to use SNDS(Smart Network Data Service) and JMRP (Junk Mail Reporting Program)
SNDS: I've subscribed and never seen anything listed here. So if you have low email volume don't expect anything to show up here
JMRP: this is a service that will send you an email when a message gets marked as spam by users. I've never got anything useful out of this either.
make sure that your DNS settings are correct (MX record, A record, PTR record). This was all correct for me and nobody could point out a flaw in my configuration.
if you open a case they'll also send you a link to "Improving E-mail Deliverability into Windows Live Hotmail". You can find this on google as well and it might give some pointers.
if you're clearly sending an email campaign add in an Opt-out link (which again was not the case for me)
even if the destination address has your email address whitelisted your mail might be silently discarded. This goes beyond all logic.
having them send an email and reply might get your email delivered as well although it looks clumsy to go ask to send you an email so you can actually use email.
Basically the filter tries to "intelligently" determine what's normal mail behavior and based on that will take actions. So there's a big chance you can get your mail delivered by improving the content of your mails.
All in all I can only recommend to not use hotmail. Not for yourself or for your customers if you're a business. Unless you always want to be doubting if the other side actually received the mail. Sometimes you might be able to call, but if this is a lead through your site and they never get your response that's lost business. Of course it's the user's choice but if you can, try to convince them to use another mail account they have as none of the other providers just silently deletes mails (or at least I've never seen it).
I hope this helps someone else.
I need to send a pdf file received from SFTP with an email as an attachment. I am just looking if this can be done without using custom pipeline component. Can this be done only with SMTP send port configuration. How can this be approached
In your orchestration your Out message must be modified like below. You must give your file list with pipe delimited list.
MessageOut(SMTP.Attachments) = "C:\\temp\atachment1.pdf|C:\\temp\atachment2.pdf";
I have a file in my folder and I want to send it to my Embedded Linux device via FTP (much like this and this and this). I know the step-by-step to do it, but I'm failing when it comes to creating the correct QUrl for it: when I call ''put'', I always get the error 301:
QNetworkReply::ProtocolUnknownError 301 the Network Access API cannot honor the request because the protocol is not known
As details, I want to save the file in a specific directory located inside a SD Card in the device, /media/mmcblk0p2/bin, and the connection doesn't have, at least for now, a password and user name defined¹. Also interesting to notice that I'm not being able to connect myself via FTP using Terminal; it always says "421 Service not available, remote server has closed connection", which is not the same problem AFAIK. (Btw I'm being able to connect via SSH using FileZilla, so it's not a hardware/physical problem)
So where is the problem? I have exactly the same code as in the mentioned links. As for now, the link I'm using is
ftp://10.1.25.10/media/mmcblk0p2/bin/center.png
(when returning the QUrl object with QDebug) and I'm not being able to make it work.
Any help would be appreciated.
¹: Btw I remember reading somewhere that when one doesn't use a user name for connecting to FTP, the system only allows the client to connect to the /ftp folder. Is that true? In that case, just calling QUrl::setUserName("root"); would suffice?
I finally discovered my problem: since I was copying the code from examples of upload to HTTP servers, I was using the function "post", specific for HTTP, instead of "put" which was the correct function to use.
Regarding the QUrl, I used QUrl urlTemp("//10.1.25.10/test.info"); while telling it to use ftp with scheme, urlTemp.setScheme("ftp");.
I do not find a way to get attachment file name without downloading the whole message using OpenPop.Net
The Pop3Client.GetMessageHeaders do not expose any data about attachments. The Pop3Client.GetMessage(messageNumber) gives attachment data but first download the whole message.
Maybe someone know how to do that?
I am the main developer for OpenPop.Net.
If you take a look at the RFC for POP3 you will notice that it is not possible to get information about attachments. To get the message headers, OpenPop.Net current sends the TOP <messagenumber> 0 command to receive headers.
Since attachment headers are located deep inside the message body, I cannot see how any POP3 client should accomplish your requirement.
IMAP is another protocol, and it includes features which allows the IMAP client to get information about each part inside a message. You might want to go in that direction.
I want to send a bunch of XML files from my client (iPad) to my application server(Web)..Is there any way I can pass them to server using HTTP POST? I assume HTTP POST only allows embedding strings not attaching as files..We don't want to use FTP due to securuty reasons. We even thought of web service, but not sure whether attachments are possible..Pleas advise if you know any ways of transferring files from client to server.
The maximum length of a POST variable is massive - so no worries there, you can send XML fine. POST can send any type of data, just make sure you set the Content-Type header correctly or you may get unexpected results.
It is no less / more secure than FTP however.
