Here a sample, try this
MFMailComposeViewController *mViewController = [[MFMailComposeViewController alloc] init];
mViewController.mailComposeDelegate = self;
//Imposto l'oggetto
[mViewController setSubject:#"Invio Copia Commissione"];
//Preparo l' A: Devo spezzare gli indirizzi E-mail
NSArray *toRecipients = [NSArray arrayWithArray:[Globals.AEmail componentsSeparatedByString:#";"]];
[mViewController setToRecipients:toRecipients];
//Preparo il Cc: Devo spezzare gli indirizzi E-mail
if ([Config.EmailAgg length] != 0) {
NSArray *CcRecipients = [NSArray arrayWithArray:[Config.EmailAgg componentsSeparatedByString:#";"]];
[mViewController setCcRecipients:CcRecipients];
}
//Setto il corpo dell'E-mail
[mViewController setMessageBody:Globals.TestoEmail isHTML:NO];
//A questo punto visto che ho fatto 30 salvo il testo anche come file allegato dell'E-mail
[Globals.TestoEmail writeToFile:[NSString stringWithFormat:#"%#/CopiaCommissione.txt", Globals.DocumentsPath] atomically:TRUE encoding:NSUTF8StringEncoding error:nil];
NSData *Allegato = [NSData dataWithContentsOfFile:[NSString stringWithFormat:#"%#/CopiaCommissione.txt", Globals.DocumentsPath]];
[mViewController addAttachmentData:Allegato mimeType:#"text/plain" fileName:#"CopiaCommissione.txt"];
[self presentModalViewController:mViewController animated:YES];
[mViewController release];
try to change mimeType in your code like this
[picker addAttachmentData:data mimeType:#"text/plain" fileName:#"log.txt"];
