Greetings, Has anyone encountered Mar 17 14:24:01 mail postfix/smtpd[32452]: SSL_accept error from unknown[166.154.120.211]: -1 Mar 17 14:24:01 mail postfix/smtpd[32452]: warning: Write failed in network_biopair_interop with errno=32: num_write=-1, provided=974 or similar using Outlook 2003 and SMTPS? Outlook reports a connection timeout, though Postfix obviously is seeing packets. I'm trying to determine why Outlook thinks Postfix isn't there, and why Postfix thinks the SSL negotiation was aborted. The op content: I'm asking in particular if any proxying[*], MTU issues, or other network creativity is known on the VZW network. PMTUd works on the Postfix end. I don't have the VZW-connected machine handy ATM to test further. SMTPS on that machine works correctly on non-VZW providers. I don't know about HTTPS, so I admittedly can't rule out PKI fun. [*] Yes, I know it would be foolish and futile to try proxying TCP/465 at the app level.
