Hi, I am using CentOS 5.9 with postfix+dovecot v1.0.7 I have problem in downloading emails with attachment of more than 3MB via my email client. (Thunderbird, Outlook, etc) I can send emails out with more than 3MB without any problem, whereas i can't download emails. Following is the error i found on maillog dovecot: pop3-login: SSL_write() syscall failed: Bad file descriptor After this the email client stops downloading emails. What could be the problem ? Please help me fix this . Thank You
You can try to increase the value of 'login_process_size' in your Dovecot configuration file. Check http://wiki.dovecot.org/MainConfig for more details.
Thanks for the reply rosehosting, yes i've already set the login_process_size to 64 and higher but the problem still persist only with dovecot-pop. Whereas dovecot-imap works fine. Any other clues to fix this problem ?
