![]() ![]() Or you used "smaller than 100" as mailnews.tcptimeout then you increased to 100? Is "default of mailnews.tcptimeout" not 100 in Tb 17 on other than Win? I use Tb 17 on Win-XP and I don't know default of mailnews.tcptimeout in Tb 17 on other OS. Therefore, "increasing the server timeout to 100" sounds pretty strange for me. I tried increasing the serverĪFAIK, default of mailnews.tcptimeout=100(sec). (In reply to Josh Berkus from comment #7) But the fact that I'm using SSL/TLS, and that some things like Inbox work fine, suggest to me that this has something to do with TB. If it's not TB's fault, then regardless TB should still fail in a more graceful way than "inexplicably cannot save sent mail or access some, but not all, folders, seemingly at random". While this might suggest that it's an issue in the network's configuration, as I said I connect using SSL/TLS and without a proxy config, and *some* folders like Inbox do work fine. This only happens on certain networks, consistently on public wifi in certain libraries. (However Inbox always seems to work, as do *some* folders I can always receive new mail.) Whenever this bug occurs, I find that I'm also never able to access Archives, nor Sent Mail, nor various other folders on that same account. It may be network-level antivirus or proxy, but I connect to both SMTP and to IMAP using forced SSL/TLS, without any special proxy configuration.Īlso note that this does not just affect Sent Mail. This is definitely not due to client-side antivirus, as I'm running TB on Ubuntu 12.04 without an antivirus. Please surely isolate this kind of "interfere of anti-virus software" and "actual delay of OK response from IMAP server", please. In this case, "actual IMAP server for Tb" is local IMAP proxy server. THUNDERBIRD FOR MAC 45.4.0 CHANGE STORED PASSWORDS SOFTWARETbport=143, IMAP proxy server by anti-virus software actual IMAP server If IMAPS,(SSL is used), this kind of virus scan is usually done by local proxy server. So, even if IMAP server returns OK response wihin reasonable time, it takes sufficiently long for Tb. And, after last data chunk is sent from Tb, virus scanner checks entire mail data, and send entire mail data to IMAP server. Virus scan for IMAP mail data by client side anti-virus software.Ĭlient side virus scanner hooks Tb's mail data send, and saves mail data in his buffer. ![]() This timeout is not so large but is never too small in ordinal environment, even if it's small for some recent IMAP servers which can be sometimes called not-so-well-configured.Ī known reason of "delay of OK response after last data chunk send in APPEND" is It's timeout for "OK response after last data chunk send in APPEND command execution". > Clearly some TB developer hard-coded a very short timeout into "save sent", (snip) (In reply to Josh Berkus from comment #11) Screen shots of the error cycle attached in a moment. So the issue appears to be server-independant as well. Note that I've encountered this error with 4 different accounts being stored on 3 different servers using 3 different IMAP software packages. Given the inconsistency in encountering the issue, I suspect that it's triggered by something happening on the server, such as a slow response in saving the message to Sent, or something else. Note that I've experienced this both on Mac and on Linux, so this appears to be a platform-independant bug.Ģ) have the Sent folder stored on the mailserver, NOT on the local machineģ) use the account to send mail for a couple of weeks In most cases, the actual message does get sent, but in a few, it appears not to have been sent. I also cannot save the message to Drafts. Repeated attempts to save the message to Sent are without result, until the "bad period" is over. The pattern is that for around 1-3 hours, any email I send will get the "error saving message to sent" error. Unfortunately, I didn't record which version of TB was specifically affected, but this happens regularly. I've been getting this error message sporadically on various accounts as well for the last 6-9 months. ![]()
