Voicemail to email works except for the attachment - timeout

Hi All,

First, thanks to everyone here and especially the developers in providing such a great program.

I have first installed a test system and was able to get everything to work (without the problem described below).

Now, with my production system, I could not get voicemail to email with attachments to work (notice with sound file). Voicemail to email without attachments works fine (notice only).

I have tried postfix mail as well without success. The error condition is “451 timeout”. Any advice or suggestions as to what to try next? Is there certain modules that I should downgrade?

Please help! I’m out of ideas as to what to try next – other than a complete reinstall.

Thank you all for helping.

Hi Obelisk,

Thanks for the tips. I had previously disabled pipelining without success. What I have done now is upgrade to Asterisk and the problem went away!

I downloaded Asterisk, did ./configure, make, and make install. So far voicemail to email with attachment is working!

Would this upgrade process cause other things to break? Thanks for your help!

It seems the server you are relaying to is having problems. Can you relay through a different one ?
You can also try disabling PIPELINING and 8BITMIME via smtp_discard_ehlo_keywords

Below is the log from sendmail and Postfix. The apparent issue is that the end-of-data command is not sent.

Would it be advisable to upgrade to Asterisk Are there other things to try?

Put in debug_peer_list in /etc/postfix/main.cf and reload postfix to see what happens when postfix is trying to send mail to pair.com.
