Open Source Cocoa/Cocoa-Touch POP3/SMTP library?

Solution 1:

MessageFramework on CocoaDev lists various possibilities,

"Sending emails from Cocoa" also lists several frameworks, including Pantomime, MailCore and EdMessage (the site for this seems to be down, but there is a mirror on github, which has also been modified to compile for 10.4, as well as 10.5 - so should work on the iPhone)

Example code using Pantomime (from the above blog-post):

CWMessage *message = [[CWMessage alloc] init];

CWInternetAddress *address;

address = [[CWInternetAddress alloc] initWithString:@"[email protected]"];
[message setFrom:address];
[address release];

address = [[CWInternetAddress alloc] initWithString:@"[email protected]"];
[address setType:PantomimeToRecipient];
[message addRecipient:address];
[address release];

[message setSubject:@"test"];

[message setContentType: @"text/plain"];
[message setContentTransferEncoding: PantomimeEncodingNone];
[message setCharset: @"us-ascii"];

[message setContent: [@"This is a simple content." dataUsingEncoding: NSASCIIStringEncoding]];

smtp = [[CWSMTP alloc] initWithName:@"smtp.gmail.com" port:465];
[smtp setDelegate: self];
[smtp setMessage: message];
[message release];

ssl = YES;
mechanism = @"PLAIN";

[smtp connectInBackgroundAndNotify];

Here is one. I have not tried it myself, but you can give it a shot...

You could also take a look at OmniGroup's open source frameworks, in particular the OmniNetworking framework. There are also a lot of other awesome components in their other frameworks you might consider using.
