[imp] SSL read operation timed out

[azurIt]

Hi,

i suddenly, sometimes, having problems with sending e-mails - after clicking on Send button, IMP is doing something for a while and then shows an error about problems with connecting to the server. This is in error log:
2014-09-23T10:15:22+02:00 WARN: HORDE [imp] PHP ERROR: fgets(): SSL read operation timed out [pid 7417 on line 105 of "/usr/share/php/Horde/Smtp/Connection.php"]

Postfix is not showing any errors so i don't assume that it's really a problem with connection, it's probaby some kind of bug related to SSL/TLS inside IMP or PHP.

I tried to disable SSL/TLS with 'secure' parameter but it's probably only for IMAP/POP3 connections because i still see these errors in log. How can i disable SSL/TLS for SMTP? Thank you.
