    Hi All,

    My environment is thus:

    Centos 5.2 - 32 bit
    ISPConfig - 2.2.32
    CPU - P4 - 2.8GHz
    Memory - 2.0 GB
    Email Client - Outlook 2003

    I can send emails fine - so long as they have no attachments. I can receive emails with or without attachments fine.

    I have accessed my emails via webmail and tried to send emails with attachments - still same problem, no joys.

    Has anyone experienced this issue before? Can anyone help resolve?

    Thanks in advance

    Hi tusshar,

    I have tried sending various attachment sizes: from 200k - 7M. Below is the anomally I see in the maillog:

    May 28 00:02:12 res postfix/smtp[2226]: 9241292877E: to=<[email protected]>, relay=mailhost.zen.co.uk[212.23.3.98]:25, delay=113779, delays=113593/0.16/0.37/185, dsn=4.4.2, status=deferred (conversation with mailhost.zen.co.uk[212.23.3.98] timed out while sending message body)
    May 28 00:49:06 res postfix/qmgr[2211]: 29568928784: from=<[email protected]>, size=1599287, nrcpt=1 (queue active)
    May 28 00:49:06 res postfix/qmgr[2211]: 97740928783: from=<[email protected]>, size=7619236, nrcpt=1 (queue active)
    May 28 00:49:06 res postfix/smtp[3329]: certificate verification failed for mailhost.zen.co.uk: num=19:self signed certificate in certificate chain
    May 28 00:49:06 res postfix/smtp[3330]: certificate verification failed for mailhost.zen.co.uk: num=19:self signed certificate in certificate chain

    Especially the bit in red. It seems as if there is a delay/defer of message transmission - because of certificate verification?

    That's just a warning. It depends on Postfix' setup if a mail is being sent while the certificate is not entirely trusted. Your mail log shows the mail gets deferred long before the message with the certificate problem so that may not be your problem after all. Try to send a mail again and search for the response (e.g. deferred like above) and then grep for all lines that have the same mail-ID (e.g. 9241292877E) so we can see the complete process. The problem must happen in the same time frame as the sending process, not that much afterwards me thinks.
    As postfix mentions "timed out while sending message body" it can't have to do with a certificate problem, as then postfix would have stopped the communication before sending any vital data.
