NOTE: I have not had any problems downloading new mail at all - before or after this bug report. I've basically had the same instance of the Thunderbird application running most of the day without running into the SMTP lookup problem. Seems to work fine / normal / as expected So it's not the virus *scan* itself (no surprise)
probably after TB checks the server for new mail a few times given the twenty or so accounts I have it checking) Thunderbird still eventually gets stuck on the "looking up smtp" step. * In scenario #2, Thunderbird bypasses Avast entirely - effectively removing Avast as a variable in the equation. in case that was causing the hang (doubtful) The idea was to take out the virus scan itself as a variable in the equation. * In Scenario #1, Avast still acts as a relay but does not actually scan inbound/outbound messages for viruses. * Scenario - disabled Avast's mail shield entirely and configured Thunderbird to connect with Google directly. * Scenario #1 - Avast mail "shield" enabled but disabled the "scanning inbound/outbound" mail messages I fiddled with some of Avast's email scanning options. I could change it to save locally, in which case that would allow for the workaround you (and general update/reply) I have Thunderbird configured to save drafts on the server (so I can access them from wherever, etc).
#AVAST AND THUNDERBIRD EMAIL FREE#
happens every time for me.įeel free to contact me if need additional information or to help isolate the problem. However, this problem appeared with upgrading to Thunderbird 3.1.6. It is possible this is a problem with Avast. Thunderbird and/or Avast is not releasing (or not properly reusing) SMTP connections. If I had to venture a guess at the problem. However, it happens even if Thunderbird is the only application running after a fresh reboot of the computer. I usually Alt-Tab to some other application and return to Thunderbird.
However, the mail send failure eventually begins after letting Thunderbird sit for a few minutes. can send mail successfully (even while it has background processing of checking and downloading messages) reason is Avast AntiVirus acts as a relay which 1) scans the plain text message for viruses 2) establishes the secure connection with google's SMTP servers (usually SSL but might use TTL too) the gmail accounts are set up with: Server Settings -> Connection Security -> "none" however some are normal gmail accounts (eg, Majority of others are Google Apps domain mail server accounts (eg, send SMTP lookup failure occurs with any of the gmail-based accounts - ie, does not appear to be specific to a Google Apps account or a normal gmail account haven't encountered problem with Yahoo but I don't use those accounts as frequently. Thunderbird manages over 20 email accounts which probably was 3.1.5 or whatever was previous since I usually do the upgrades) but I don't recall it occurring in my previous TB install. Thunderbird release v3.1.7 (happens very very very frequently) Obviously, connecting and sending the mail message is desired. Thunderbird dialog appears of "Looking up. Close and restart Thunderbird (including closing any open compose messages) Copy message content to clipboard (and or a text file) User Agent: Mozilla/5.0 (Windows NT 6.1 WOW64 rv:9.0.1) Gecko/20100101 Firefox/9.0.1Ĭomposed mail message - Subject: Test Message: Test
