[SOLVED] iPhone SMTP troubles....

[natrixgli]

Hi,

I have SMTP working with AUTH & SSL/TLS on my Zimbra server, however my iPhone keeps saying it can't find the server.

I can use Thunderbird/Windows Mail/Outlook to send. (My iPhone is on the same subnet as the computer that CAN send mail)

Anyone have suggestions? I have Zimbra running on another host that CAN send mail with the iPhone using the exact same settings.

When I send mail via the WORKING zimbra server, this is what I see in the logs:

Aug 11 15:05:14 mail postfix/smtpd[11679]: connect from CPE-24-211-0-77.wi.res.rr.com[24.211.0.77]

Aug 11 15:05:15 mail postfix/smtpd[11679]: TLS connection established from CPE-24-211-0-77.wi.res.rr.com[24.211.0.77]: TLSv1 with cipher AES128-SHA (128/128 bits)

Aug 11 15:05:16 mail postfix/smtpd[11679]: disconnect from CPE-24-211-0-77.wi.res.rr.com[24.211.0.77]

When I try to send from the NON WORKING server, I see this:

Aug 11 15:09:13 apollo postfix/smtpd[21660]: connect from CPE-24-211-0-77.wi.res.rr.com[24.211.0.77]

Aug 11 15:09:13 apollo postfix/smtpd[21660]: TLS connection established from CPE-24-211-0-77.wi.res.rr.com[24.211.0.77]: TLSv1 with cipher AES128-SHA (128/128 bits)
Aug 11 15:09:14 apollo postfix/smtpd[21660]: lost connection after EHLO from CPE-24-211-0-77.wi.res.rr.com[24.211.0.77]
Aug 11 15:09:14 apollo postfix/smtpd[21660]: disconnect from CPE-24-211-0-77.wi.res.rr.com[24.211.0.77]

Note the username is sent using the WORKING server, but it seems to fail with the NON working server. I've gone over the settings hundreds of times in the iPhone, and everything looks identical between the two servers.

The working server is Zimbra 4.5.3, the non-working server is Zimbra 4.5.5

Update:


A full restore of my iPhone fixed the problem. I knew it had to be the phone since all other clients were working just fine.

Just thought I'd add to this as I've just experienced similar problems connecting my iPhone to Zimbra.

I had to uncomment secure smtp in /opt/zimbra/postfix/conf/master.cf.in as per this thread: SMTP Submission Port
